High

Base vector

AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Name of the Vulnerable Software and Affected Versions: ProcessMaker versions prior to 3.5.4

Description: An unrestricted file upload vulnerability exists due to improper handling of uploaded plugin archives. An attacker with administrative privileges can upload a malicious .tar plugin file containing arbitrary PHP code. Upon installation, the plugin’s install() method is invoked, resulting in execution of attacker-supplied PHP code on the server with the privileges of the web server user. This vulnerability can be chained with a privilege escalation flaw to achieve full remote code execution from a low-privileged account.

Recommendations: Update to version 3.5.4 or later.
